I understand if you have too much time
to deal with things like this.
Anyways posted a few days ago, had no response,
so I decided to post again, except add marcel to the
CC. Anyways I seem to be hitting this during

wake up this triggers.(not all the time though)

here's a cutout of upon waking the mouse up
from sleeping(not s2ram)
